Intuit QuickBooks Online is not well positioned for complex account structures. To avoid such restrictions, ScheduleInterpreter developers built a manual override, enabling any organization using Intuit's product, connect any customer account in QuickBooks Online to any customer account in ScheduleInterpreter. This new feature helps to solve CustomerRef is required error, one of the most common errors when synchronizing data between two platforms. Option is available to all subscribers under ACCOUNT CENTER.
